Moto 360 (2nd gen) vs Asus Zen Watch

The Moto 360 is one of the few watches which will change the brightness depending on how bright the area is around you. This is very convenient when you use the watch outdoors as you don't have to manually adjust the brightness each time you step outside. The light sensor is located in the small black semi-circle at the bottom of the display.

With minimal bezels, the Moto 360 looks stunning. While it does have a 'flat tire', it's pretty small and required to have such slim bezels as well as the ambient light sensor.

Through Moto Maker you can choose either a 42mm or 46mm size, the bezel color, case color, band (2 leather options or 3 metal options), and the default watch face.

The larger 46mm size, micro knurl bezel, gold case or metal bands will increase the price slightly.

This smartwatch has powerful hardware (for a watch) and costs only $99. It's the best value smartwatch out there that doesn't compromise much on design - arguably the most important factor when choosing a smartwatch.

The Amoled display provides rich colors are true blacks which is even more important on a watch (likely it will be displaying black very frequently). From a functionality standpoint, a square display fits more content on it, especially when the entire UI is based on rectangular cards.

The bio sensor measures your pulse, and keeps track of your relaxation level throughout the day (a lower pulse means you are more relaxed). It's neat to see what part of the day you are stressed out during, and if you notice patterns during high stress times you can change that.
